Study of 20 Hz high spatial-temporal resolution monochromatic X-ray dynamic micro-CT

He jishu, 2023
BackgroundDynamic micro-computed tomography (micro-CT) using monochromatic X-ray offers higher density resolution and lower radiation damage compared to that using white X-ray, however balancing its imaging spatial and temporal resolution is challenging.

Study of the Microfocus X-Ray Tube Based on a Point-Like Target Used for Micro-Computed Tomography. [PDF]

PLoS ONE, 2016
For a micro-Computed Tomography (Micro-CT) system, the microfocus X-ray tube is an essential component because the spatial resolution of CT images, in theory, is mainly determined by the size and stability of the X-ray focal spot of the microfocus X-ray ...

X-ray computed micro-tomography of reticulated vitreous carbon [PDF]

Carbon, 2018
Abstract The 3D structure of various grades of reticulated vitreous carbon (RVC) is studied by X-ray computed micro-tomography (μCT). The settings required to estimate the bulk volumetric surface area, Ae, accurately are investigated and the results are compared to those obtained from scanning electron microscopy and from pressure drop measurements ...
